The Atair Viper, which is no longer produced, flew almost exactly like a Stiletto. I had a 150 for a while in my demo rig and loved it. It is a fully eliptical nine cell parachute. They came stock with kill-line sliders and pilot chutes. They are very easy to pack as they are made out of the non-slippery Gelvenor Textiles zero-p, just like a Triathalon, Cobalt, etc. Openings are sweet and on heading. Landings are every bit as sweet as a Stil. Like previously posted, you can get them for quite a bargain on the internet classifieds. Like the ones here, and at www.enclave.com
